Integrated Smart Grid simulations for generic automation architectures with RT-LAB and mosaik

Abstract

Although, a variety of established tools for analysis of power systems already exists, it is in the medium term very unlikely that one of these tools alone will provide all functionalities and models that are required to simulate future Smart Grids in all its facets. This is mainly due to the high number of Smart Grid use cases, actors, and technologies to be integrated that is not known from other industries so far. Accordingly, a mixture of various different and established tools will be required. These, again, have to be composed in use cases specific to complex and system-wide scenarios. Therefore, tools such as simulation platforms and -suites are required that are additionally capable of integrating software-and hardware models and components. Therefore, the proposed approach is an integrated concept allowing for analyzing large-scale scenarios taking into consideration both, stationary and dynamic simulations in real-time.

Requirements for Power Hardware-in-the-Loop Emulation of Distribution Grid Challenges

“…The approach focuses on long-term evaluations comprising large simulations without considering smart grid technologies. [2], [3] Kochanneck et al, 2018, Karlsruhe Institute of Technology (KIT), Germany, are coupling a smart residential building (see Section V-A) with a co-simulation of a suburban low voltage distribution grid comprising intelligent buildings. The real building is connected to an artificial mains and a PVsimulator to emulate the most important electrical influences to the building.…”

Cyber-physical energy systems modeling, test specification, and co-simulation based testing

“…Mosaik 2 (e.g. [17], [18]) is an enhanced, streamlined version of the software that is purely based on Python and provides more concise and flexible APIs.…”

A Real-Time Testbed Environment for Cyber-Physical Security on the Power Grid

“…In an effort to implement a co-simulation idea, specifically for the smart power grids as a case of CPSs, Buscher, et al [2], provided an OpenSource framework, the so-called "mosaik", which enables the functional coupling of different software simulators, emulators, and hardware setups. In fact, mosaik's main goal is to make use of existing simulators and other tools in a common context which means letting each component to execute processes with its own individual event loop and just controlling the synchronization of participants and managing the exchange of data among them.…”
